The accuracy requirements of motorcycle forgings usually include the following aspects: Dimensional accuracy: The dimensional accuracy of motorcycle forgings refers to the deviation between the shape and size of the parts and the requirements of the design drawings. Generally speaking, the dimensional accuracy of motorcycle forgings is required, especially for key parts that are matched with other parts, such as crankshaft, piston, and so on. The dimensional accuracy of these parts directly affects the performance and running stability of the engine. Geometric shape accuracy: The geometric shape accuracy of motorcycle forgings refers to the deviation between the surface shape and geometric features of the parts and the design requirements. For example, the roundness and flatness of the motorcycle crankshaft and the roundness of the gear need to meet certain accuracy requirements to ensure the assembly and normal operation of the parts. Surface quality: The surface quality requirements of motorcycle forgings are high, mainly in order to reduce the friction loss of parts during use and prevent surface initiation cracks. Common surface quality requirements include surface finish, removal of rust, scratches and dents, etc. Material properties: The material properties of motorcycle forgings refer to the mechanical properties and physical properties required by the parts during use. For example, engine blocks need to have good strength, hardness and wear resistance to withstand high temperature and high pressure working environments. In addition, motorcycle forgings also need to have good toughness and tensile strength to ensure that there will be no fracture or deformation under severe loads. In short, the accuracy requirements of motorcycle forgings are to ensure that the parts meet the design requirements and the safe and reliable operation, but also closely related to the quality and performance of the motorcycle.
